A tube, I, extendsfrom beneath the slide D to they yinvention relates' *to a machine ofthat class rear ot a shovel-plow or trench-opener, J, suitably which issupported by a single wheel, provided with braced from the frame, and inthe same vertical plane l pins onlts face, arranged at any desireddistance as the wheel G.

This scraper embraces the shank of the correspondingwith the distances between the pins on plow, and has wings projectingout from the plow, and the wheel. 1

The improvements herein claimed consist- -tlIe plow-shank, and held bymeans of set-screws, k,

trench, and some of the loose .earth at its sides is pushed back iu thetrench upon the seed and covers them. v

When the pin has passed the end of the lever, and

grass and weeds removed before thc seed is deposited.

In ythe accompanying drawing- .Figure 1 represents a side elevation ofmy machine, partly in section, at the line a; :c of iig. 2.

Figure L, a horizontal section of the same at the line y y ofig. 1; and

Figure 3, a section at the line z z of iig. l.

i A representsa stout frame, in this instance, recta-ngular in form, bythe upright-s B of which is supported a hopper, C, to'contain the cornor other seed to be planted. f

Beneath the hopper is a slide, D, havingan open- Ving,'d, nean its frontend i y A plate spring, E, is-sccured at one end,to the front slide,forces it back u ntil its shoulder strikes the hophoppcr, and the leverto its former position, when another pin strikes it, and theabove-dsribed opent-- tion is repeated.

lt will be seen that, by turning the screw H, the slide may be forcedforward, so that only 1a portion of the opening (l is allowed' to enterthe hopper, or that, by turning the screw the other way, the opening isbrought wholly within the hopper, whenthe slide is forced back by thespring.

.,lhe quantity of' seed planted after cach -forward movement of theslde'is thus easily regulated. The slide maybe removed when desired byremoving the block D'. y

I am aware that it is not new toV operate the seedn distributingmechanism of a scodfplant-er by means of ward end of the slide D. Y

The slide rests upon anemovable block, D', supportedon the frame, andisprovided with shoulders d', d at its ends. i

A pendulous rod or levexgF, is pvoted at its upper The broadsupportingwhccl then passes over the allows it to escape, the spring E,bearing against the per, bringing the opening or sced-cap d within thepins or cams on a. wheel, and do not, therefore, broadly claim a.ymachine so constructed.

W hat I claim isf 1. The combination of the ducting-tube, the hopper,bearing against theA slide, the pendnlous lever, th supporting-wheel`and its pins, all these parts being constructed to operatesubstantially as'set forth.

2. The combination of the reciprocating seed-slide,

trench-opener, the conthe secds1i 1e, the spring,

the pendnlons lever, forth.

and the adjust-ing screw, as set :ill `these forth.
